Some 2018 years ago the Kingdom of Jesus Christ was established on planet Earth. However, Protestants do not really know it. Actually, they do not like to connect the two festivities; because that would imply that the Catholic and Apostolic and Only One Church of Christ was established as the Millennial Kingdom of Christ on Earth (Protestants are still waiting for the coming of the Messiah, as well as Muslims wait for the 12th Imam). However, the reality is that God has been ruling the Earth for 2018 years, Emmanuel, God amongst us in the Eucharist.
Now we finally know how to preach the Gospel of Eternity with four numbers: 2018. For indeed, every time we sign a document and put the date, we remember the birth of our savior.
I may add as a reminder that we, Christians, are his only Church. We have been placed on Earth by God as his Time Keepers, Guardians of Time. Our mission is to remind everyone that Jesus was born 2018 years ago, he died, he resurrected, and he will come again in Glory to judge the living and the death. We are also reminded that the Gates of Hell shall not prevail against the Church; thus we will keep reminding this date until the day he comes in Glory, which is the Second Coming, the End of the World (Earth and this Universe, that is).
